New Evidence for an Apple a Day

The old adage promoting an apple a day for better health just got a boost from science. A large Dutch study has found that eating apples and pears is associated with a lower risk of stroke.

The findings counter the widespread belief that the most healthful fruits and vegetables are those that come in deep, rich colors inside and out. The dark green of spinach and deep red of raspberries are produced by phytochemicals that are associated with better heart health and lower rates of cancer, prompting the common advice to “eat your colors.” Apples and pears, although red, light green or yellow on the outside, are typically considered “white” fruits because the inside of the fruit, which represents the largest edible portion, is white.

Researchers in the Netherlands decided to track fruit and vegetable intake based on the color of the largest edible portion of the food. The categories were green (broccoli, kale, spinach and lettuce), orange/yellow (oranges, carrots and peaches), red/purple (cherries, grapes, beets and tomatoes) and white (apples, pears, bananas and cauliflower).

The investigators analyzed data collected from 20,069 men and women who took part in the Dutch Morgen study, which stands for Monitoring Project on Risk Factors and Chronic Diseases. All the participants, ages 20 to 65, were healthy and free of cardiovascular disease at the start. The study subjects filled out food questionnaires detailing their eating habits. Read more
